Abstract

본 발명은 전화기에 관한 것으로 국선측으로부터 착신신호가 검출되거나 사용자가 특정 상대방을 호출하여 통화하고자 할시 발생되는 송수화수단의 오프훅 신호를 검출하여 키패드 및 표시수단에 후광조명을 제공하여 전화기 사용에 편리성 및 신뢰성을 제공하도록 한 것이다.The present invention relates to a telephone and detects an off-hook signal of a handset means generated when an incoming signal is detected from a CO line or when a user wants to call a specific counterpart to provide a backlight with a keypad and display means. It is to provide convenience and reliability.

Description

전화기의 후광조명방법 및 장치Backlighting method and apparatus for telephone

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

Claims (2)

전화기에 있어서, 송수화 수단의 오프훅 신호를 감지하면 통화모드로 전입함과 동시에 전화기가 사용되는 주변의 광도를 측정하는 제1단계와, 상기 제1단계에서 측정된 광도값과 메모리수단에 설정된 기준광도값을 비교하여 측정광도값이 기준광도값 보다 큰지의 여부를 검출하는 제2단계와, 상기 제2단계에서 측정광도값이 기준광도값 보다 크면 후광조명을 수행하지 않고 측정광도값이 기준광도값 보다 적으면 후광조명을 수행하며 카운터 수단을 구동하여 소정시간을 카운팅하는 제3단계와, 상기 제3단계의 카운팅시간 이내에 키입력수단으로부터 새로운 키신호를 검출하면 시간카운팅을 리셀하여 처음부터 카운팅하며 새로운 키신호를 검출하지 못하면 카운팅 완료후 후광조명을 오프시키는 제4단계를 포함하는 것을 특징으로 하는 전화기의 후광조명방법.In the telephone, when the off-hook signal of the handset means is detected, the first step of entering the call mode and measuring the luminance of the surroundings of the telephone used, and the luminance value measured in the first stage and the memory means A second step of detecting whether the measured brightness value is greater than the reference brightness value by comparing the reference brightness value, and if the measured brightness value is larger than the reference brightness value in the second step, the measured brightness value is not performed without performing backlighting. If the brightness value is less than the third step of performing backlighting and counting a predetermined time by driving the counter means; if a new key signal is detected from the key input means within the counting time of the third step, the time counting is re-scheduled from the beginning. After counting, if the new key signal is not detected after the completion of the counting comprises a fourth step of turning off the backlight; How to light. 전화기에 있어서, 송수화 수단의 오프훅 여부를 검출하여 그에 해당하는 신호를 출력하는 오프훅 감지수단과, 송수화수단의 오프훅의 검출될시 전화기가 사용되는 주변의 광도를 측정하는 광도 측정수단과, 상기 측정된 아날로그 광도신호를 디지탈 신호로 변환시키는 A/D 변환수단과, 전화기 사용에 대한 전반적인 키신호를 입력하는 키입력수단과, 전화기의 사용에 따른 동작상태를 디스플레이 하는 표시수단과, 후광조명에 대한 기준 광도 데이타 및 전화기 사용에 대한 전반적인 프로그램 데이타가 저장된 메모리수단과, 후광조명에 대한 소정시간을 카운팅하는 타이머수단과, 후광조명 구동에 대한 전반적인 동작을 제어하는 후광조명 제어수단과, 전화기의 전반적인 동작을 제어하는 제어수단 및, 후광조명 온, 오프를 스위칭하는 후광조명 구동수단을 구비하는 것을 특징으로 하는 전화기의 후광조명장치.A telephone, comprising: off-hook detection means for detecting whether the handset means is off-hook and outputting a signal corresponding thereto; and luminous intensity measuring means for measuring the brightness of the surroundings of the telephone when the off-hook of the handset is detected. And A / D conversion means for converting the measured analog light signal into a digital signal, key input means for inputting an overall key signal for using a telephone, display means for displaying an operation state according to the use of the telephone, Memory means storing reference brightness data for backlighting and overall program data for telephone use, timer means for counting a predetermined time for backlighting, backlighting control means for controlling the overall operation for backlighting driving; Control means for controlling the overall operation of the phone, and backlight backlight drive for switching the backlight backlight on and off Backlight illumination device of the telephone, characterized in that it comprises the stage. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
